Right, for people as famous as Banksy and nobody else, that’s partly what I’m talking about. Sure legal murals get protected all the time but writers/bombers (like King Robbo who banksy dissed,) and even most “street artists” who don’t write, (like Blek Le Rat, who Banksy bit) get chased by the cops (or train yard bulls), it’s the name of the game, and frankly it wouldn’t be as fun without it.
